In circle P, diameter QS measures 20 centimeters. Circle P is shown. Line segment Q S is a diameter. Line segment R P is a radius. Angle R P S is 123 degrees. What is the approximate length of arc QR? Round to the nearest tenth of a centimeter. 9.9 centimeters 19.9 centimeters 21.5 centimeters 43.0 centimeters

Length of arc QR is 9.9 cm

Step-by-step explanation:

Given that circle P, i.e. center is point P.

QS is diameter with length 20 cm.

Given that RP is the radius with

To find length of arc QR = ?

Solution:

Arc QR subtends the on center P.

So, we need to find the angle to find the length of arc QR.

QS is the diameter so

Converting in radians,

Using the formula for length of arc:

Where is the angle subtended by the arc on center.

R is the radius of circle.

Here,

Length of arc QR is 9.9 cm

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
